摘要
以内燃机排气歧管热应力问题为例,分析了流-固-热弱耦合模拟中3种不同的数据传递方法各自的优缺点;介绍了4种有限元实体单元,对它们在计算精度、计算时间和对计算机硬件的要求等方面做了比较。
Taking the thermal stress problem of ICE exhaust manifold as an example, the advantages and disadvantages of three data transfer schemes in fluid-solid-heat weak coupling simulation are analyzed ; Four types of finite solid elements are presented with their calculation accuracy, computing time and computer hardware requirements compared.
